CHARLES H. FALK, OF KINSLEY, KANSAS.

THRESI-HNG MACHHNE.

SPECIFICATION forming part of Letters Patent No. 6'72A42, dated April 23, 1901.

Application filed April 9, 1900. Serial No. 12,169. (No model.)

To all whont it may concern:

Be it known that I, CHARLES H. FALK, a citizen of the United States, residing at Kinsley, in the county of Edwards and State of Kansas, have invented certain new and useful Improvements in Threshing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

This invention relates to threshingmachines; and it consistsin the novel construction and combination of the parts hereinafter fully described and claimed, whereby the chaff and light rubbish are removed.

In the drawings, Figure 1 is alongitudinal section of part of a threshing-machine constructed according to this invention. Fig. 2 is a plan view of the blast-pipes. Fig. 3 isa plan view showing a modification in the arrangement of the blast-pipes. Fig. 4 is a cross-section through one of the blast-pipes.

A is the casing of the threshing-machine. B is the threshing-cylinder, and a is the inclined feed-board, down which the sheaves are fed into the cylinder after the bands are cut. 0 is a grate over which the straw is carried by a reel O. D represents the heaters or straw-feeders, between which the straw is passed, and D are the straw racks or shakers, which extend through the middle and rear parts of the machine. E represents the bot toms, upon which the grain falls from the various separating devices above them. All these parts are of any approved construction.

F is a blast-fan or blower arranged under the feed-board a in front of the threshingcylinder. This fan is of any approved construction and is driven in any convenient manner.

Grepresen ts the blast-pipes, which are connected to the outlet of the fan-casing and which form a tortuous air-conduit under the separating devices of the threshinganachine.

In Fig. 2 the blast-pipes consist of a longitudinal main pipe connected to the fan-casing and provided with lateral branches.

In Fig. 3 the blast-pipes G are one con tin uous main pipe, with longitudinal and transverse portions arranged so as toform a tortuous air-conduit.

The transverse portions 9 of the blast-pipes are provided with perforations or slits 9, through which the air passes.

H represents regulat-ingpipes journaled on the perforated portionsg of the blast-pipes. Each pipe H has a longitudinal slot h and is provided with projecting guide-lips h at the edges of the slot, so as to direct the blast. The regulating-pipes are revolved upon the blast-pipes to adjust the amount and direction of the blast.

I represents operating-levers secured to the pipes H, and I is a coupling-rod which. connects all the levers together, so that the regulating-pipes can be adjusted simultaneously. The transverse portions of the blast-pipes are arranged parallel with each other in aseries at any desired distance apart, and the air proceeding from their perforations or slits is projected rearwardly and upwardly, so that the chaff and light rubbish are blown upward and rearward and are discharged out bf the rear end of the th reshingmachine.

What I claim is 1. In a threshing-machine, the combination, with grain-separating mechanism, of a series of blast-pipes arranged transversely under the said separating mechanism and provided with perforations, and means for regulating the air-outlet openings of the perforations of all the said pipes sim ultaneously,

substantially as set forth.

2. In a threshing-machine, the combination, with a threshing-cylinder, and grainseparating mechanism; of a longitudinal main blast-pipe provided with a series of branches extending crosswise throughout the machine under the said separating mechanism, the first branch of the series being ar-' ranged between the threshing-cylinder and the separating mechanism, and all the said branches being provided with perforations; and means for regulating the air-outlet open- 10 naled on the said transverse portions, and

means for turning all the said regulatingpipes simultaneously, substantially as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

CHARLES H. FALK,
